Yes, all are different ways of saying - now, at this time, immediately, at this juncture, at this stage...

"At this point in my life I don't think it's important to have a 9 to 5 job." "At this point in time I don't think we need a new car."

It is used when you want to emphasize a specific time or occurrence. Occurrence - "At this point, we should have realized that things would turned out differently." Specific Time - "The bus would arrive at this point."
